Two new Green CryoTech cryogenic systems have been developed: the CO2 Hybrid, which can be fitted to a conventional diesel-powered truck cooling system to supplement the pull-down capability; and the ST-CR which provides solutions for both single and multi temperature truck operations. There is also a new multi-temperature trailer system in development.
Although Thermo King’s CO2 technology is not the only cryogenic solution available, it offers an innovative system which both provides airflow in the load space, which is essential for fresh produce, and exhausts the cryogen outside the load space. The Thermo King Green CryoTech units do not allow CO2 to enter the cargo area unlike other systems that inject liquid coolant directly into the cargo area. This provides a significant health and safety benefit.
In addition, fewer moving parts in the cryogenic system than in a conventional system ensure that the unit has higher reliability, longer life and lower maintenance. And with no lubricants to dispose of there is less impact on the environment.
